Outcomes

Primary Outcome Measures

Progression-Free Survival (PFS), Core Radiology Assessment

Progression-free survival (PFS) = time from randomization to first documentation of objective tumor progression or to death due to any cause, whichever occured first. If tumor progression data included more than 1 date, the first date was used. PFS = first event date minus the date of randomization + 1. On study included treatment plus 28-day follow-up periods.

Progression-Free Survival (PFS), Investigator's Assessment

Progression-free survival = time from randomization to first documentation of objective tumor progression or to death due to any cause, whichever occured first. PFS = first event date minus the date of randomization + 1). On study included treatment plus 28-day follow-up periods.

Secondary Outcome Measures

Objective Response, Core Radiology Assessment

Objective response (OR) = the number of patients with confirmed complete response (CR) and confirmed partial response (PR) according to the Response Evaluation Criteria in Solid Tumors (RECIST) criteria, relative to all randomized patients. CR was defined as the disappearance of all target lesions. PR was defined as a ≥ 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions. Confirmed responses (CR or PR) = those that persisted on repeat imaging study >= 4 weeks after initial documentation of response.

Objective Response, Investigator's Assessment

Objective response (OR) = the number of patients with confirmed complete response (CR) and confirmed partial response (PR) according to the Response Evaluation Criteria in Solid Tumors (RECIST) criteria, relative to all randomized patients. CR was defined as the disappearance of all target lesions. PR was defined as a ≥ 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions. Confirmed responses = those that persist on repeat imaging study >= 4 weeks after initial documentation of response.

Overall Survival (OS)

Overall survival (OS) = time from date of randomization to date of death due to any cause. For patients not expiring, survival time was censored at the last date they were known to be alive. Patients lacking data beyond randomization had their survival times censored at the date of randomization with a duration of 1 day.

Time to Tumor Progression (TTP), Core Radiology Assessment

TTP = time from randomization to first documentation of objective tumor progression. TTP data were censored on the day following the date of last on treatment (including 28 day follow-up period) tumor assessment documenting absence of progressive disease for subjects who did not have objective tumor progression while on treatment or who were given anti-tumor treatment other than study treatment prior to documentation of objective tumor progression. Subjects with no tumor assessments after randomization had TTP censored on the date of randomization with a duration of 1 day.

Time to Tumor Progression (TTP), Investigator's Assessment

TTP = time from randomization to first documentation of objective tumor progression. TTP data were censored on the day following the date of last on treatment (including 28 day follow-up period) tumor assessment documenting absence of progressive disease for subjects who did not have objective tumor progression while on treatment or who were given anti-tumor treatment other than the study treatment prior to documentation of objective tumor progression. Subjects with no tumor assessments after randomization had TTP censored on the date of randomization with a duration of 1 day.

Duration of Response (DR), Core Radiology Assessement

Duration of response (DR) = time from the first documentation of objective tumor response to the first documentation of objective tumor progression or to death due to any cause. DR data were censored on the day following the date of the last on treatment (including 28 day follow-up period) tumor assessment documenting absence of progressive disease for subjects without objective tumor progression who did not die due to any cause while on treatment or who were given anti-tumor treatment other than study treatment prior to observing tumor progression.

Duration of Response (DR), Investigator's Assessment

Duration of response (DR) = time from the first documentation of objective tumor response to the first documentaion of objective tumor progression or to death due to any cause. DR data were censored on the day following the date of the last on treatment (including 28 day follow-up period) tumor assessment documenting absence of progressive disease for subjects without objective tumor progression who did not die due to any cause while on treatment or who were given anti-tumor treatment other than study treatment prior to observing tumor progression.

EuroQoL Five Dimension (EQ-5D) Health State Index

EQ-5D Health State Index: a brief, self-administered generic health status instrument. Respondents were asked to describe their current health state on each of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety or depression) on a three-level scale (1=no problem, 2=some problem, and 3=extreme problem). A maximum score of 1 can be derived from these 5 dimensions by score conversion; range: -0.39 (worst health state)to 1.00 (best health state). This descriptive system classifies respondents into one of 243 possible distinct health states (EQ-5D descriptive system).

Euro-QoL Visual Analog Scale (EQ-VAS)

EQ-VAS: overall self-rating rating of the patient's current health state using a 20 cm Visual Analog Scale (EQ-VAS), also called the health state thermometer) is a metric measurement (in 2 mm interval) from the visual analog scale which ranges between 0 (worse imaginable health state) and 100 (best imaginable health state).

Plasma Concentrations of Soluble Proteins: Plasma VEGF-A, Plasma VEGF-C, Plasma sVEGFR-3, PLASMA IL-8, and PLASMA bFGF That May be Associated With Tumor Proliferation or Angiogenesis

Plasma concentrations of soluble proteins that may be associated with tumor proliferation or angiogenesis collected from a subset of patients were analyzed by enzyme-linked immunosorbent assay (ELISA) analysis. Soluble protein values: Baseline concentration (pM) and ratio to Baseline at each timepoint; ratio = plasma concentration of soluble protein (picograms per milliliter [pg/ml]) at timepoint / concentration of soluble protein (pg/ml) at baseline. Samples below the limit of quantitation and samples with insufficient volume available were excluded.

Incremental Cost Effectiveness Ratio (ICER)

Incremental cost effectiveness ratio (ICER) of sunitinib compared to IFN-a as first-line treatment for MRCC, defined as the ratio of the incremental cost of treatment over the incremental effectiveness; effectiveness measured as quality adjusted life year (QALY) gain. This objective was not addressed in the clinical study report, but an interim analysis of cost-effectiveness was presented separately. These results were not available for inclusion at the time of this posting.

Ctrough Concentrations of SU011248

Subject observed Ctrough (trough drug) concentrations of SU011248 per cycle and study day determined by plasma trough samples collected from a subset of patients. Steady-state observed trough concentrations were dose corrected to the starting dose (reference dose) where appropriate. Concentrations below the limits of quantitation (BLQ) were set to 0. Ctrough = minimum (trough) plasma concentration (nanograms per milliliter [ng/mL]).

Ctrough Concentrations of Metabolite SU012662

Subject observed Ctrough (trough drug) concentrations of active metabolite SU012662 per cycle and study day determined by plasma trough samples collected from a subset of patients.
